Babies born with fetal alcohol syndrome are proof that alcohol is a teratogen

Explanation:  

A teratogen is an agent that causes an abnormality for the fetus  during pregnancy . Drinking alcohol during pregnancy causes Fetal Alcohol Syndrome.This is because the alcohol passes through the blood and get into the womb thereby reaches the fetus.  

Alcohol disturbs the nutrition and oxygen delivery for the baby in the mother’s womb. The development of organs and tissues is also affected due to alcohol consumption. Alcohol also causes permanent brain damage in the baby. Hence alcohol is considered as a teratogen in fetal alcohol syndrome.

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )
